Specification of Letters Patent.` Application led May 17, 1913.

Patented Dec. 30,1913. serial No. 768,246.

My invention relates to irons of the type having self-contained heating means; and the object of my invention is to provide a structure simple in construction and mode of operation, having means insuring the dis-` t-ributiron of heat atV the points desired, with ample provision for ventilation and the supply of air to the interior thereof.

A further object of my invention is to provide a structure that will be relatively cool adjacent the handle. And a still further object is to provide such an iron with an improved burner designed to be safe under all conditions, and with an improved gascontrolling valve so constructed as to prevent cutting od the supply of gas to the burner before the main valve is closed.

These and other features of my invention will be more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a longitudinal sectional elevation on the line 1 1, Fig. 2, of a gas heated iron having and containing the improvements forming the subject of my invention; Fig. 2, is a sectional plan View on the line 2 2, Fig. 1; Fig. 3, is a cross sectional view on the line 3 3, Fig. 1; Fig, 4, is a sectional view of the burner, slightly enlarged, taken on the line 4 4, Fig. 1; Fig. 5, is a perspective view of the flame deflector; Fig. 6, is a `sectional View of the gas supply or burner tube carried by the iron and the valve controlling the supply of gas to the iron, and Fig. 7, is a cross-sectional View on the line 7 7, Fig. 6. l

In the drawings, 1 representsthe body of the iron, which may be cast hollow and `is in a single piece; said body having a series of perforations 2 in its walls extending substantially the length of the iron and disposed adjacent the top of thesam'e, and at the rear a plurality of apertures 4 which open through'said walls 3 of the iron into the chamber thereof adjacent the bottom of the same in the form of semicircles; recesseswithin the walls of the iron forming said apertures being circular so that there will be no undue trouble or expense in providing the semicircular apertures piercing the wall of the iron.

The iron is provided with the usual handle 5, which may be secured thereto by screws 6; ,spacing nuts or washers 7 being interposed between the lower portion of the handle and the body of the iron.

Hthin the iron is a heat or flame deflecvtor 8, which extends substantially throughout the inner chamber of the same and has a forward end 8a which is bent or curved downward slightly so as to deflect the desired quantity of heat into the toe of the iron, and this deector may be held in place by means of a screw 11 passing through the top wall of t-he iron and engaging a recess 12 formed in the top of said deflector. The front end or forward portion 8a of the deflector is preferably provided with a series of ventilating notches 13 in its sides which lie adjacent to or come in contact with the side walls of the iron. The deflector is substantially centrally disposed within the iron and its side walls 14 are preferably spaced from the side walls of the iron as shown in Figs. 2 and 3, and the deector walls are preferably notched on the bottom, as indicated at 14a; the notches being so placed and spaced as to be substantially intermediate the apertures 4 adjacent the bottom of the iron. These several apertures and notches in the walls of the iron and in the walls of the deector serve to insure the presence of a suiicient quantity of air to support combustion, while the apertures adjacent the top of the iron insure proper vent for excess of heat and products of combustion. Y

Secured to the rear open end of the body of the ironis a burner comprising a shell 15, having a portion 16 which may engage a notch 17 in the base of the iron; said shell having an upper projection 18 with a recess or socket 19 for engagement by a set screw 20 carried by the top wall of the iron body. The chamber 21 of this burner shell may be and preferably is substantially egg-shaped, as clearly indicated by the sectional views of the same, and is provided at its inner end adjacent the guard with a wire screen or flame surface 22, held in place by a retaining ring 22a, This retaining ring extends into the chamber 21, holding the screen 22 in place and forms an annular outlet passage beyond said screen. This wall of this burner shell is provided with the usual air inlet spaces communicating with the chamber of the iron and indicated at 23; being disposed on opposite sides of said burner shell.

Carried by the burner structure is a gas supply tube 25, having a hose connecting nipple 26; said tube being notched or slotted at 27 for the inlet of air to mix with the gas and support combustion, and with a valve sleeve 28 to adjust the area of the openings formed by said slots or notches, which sleeve is confined against extreme movement by a set screw or other stop 29.

The gas supply tube is provided with an apertured wall 30 having a needle valve 3l, which may be of any approved type, controlled by a screw member 82, having a cam 33 for action upon the lower end of said valve when it is desired to close the same; a springbeing employed to open the valve whenthe camis disengaged therefrom. In the usual burner devices for gas heated irons, this valve is arranged to entirely close the gas inlet opening, and is operated when it is desired to cut down or entirely cut oft` the supply of gas after the iron heats up.

It is highly dangerous to throw the gas pressure onto the rubber tube employed as a conduit for the gas, and insurance underwriters object to the practice. To obviate any danger, I flatten the point of the needle valve, as indicated at 35, so that when it is seated it can not entirely close the aperture in the wall 30, and hence enough gas will pass to form a pilot flame. I/Vhen this pilot flame is in use, the supply of air entering via the slots 27 may be cut down by means of the sleeve valve 28.

I claim:

1. In a gas heated iron, the combination of a body portion having a plurality of apertures in its side walls adjacent the top of the same, a plurality of apertures in said side walls adjacent the bottom of the same and disposed at the rear of said body, said latter apertures opening outwardly below the plane of the inner surface of the iron bottom, a burner connected to the rear of said iron, and a flame deflector detachably mounted within the iron, said flame deflector having a downwardly curved forward end disposed adjacent the toe of the iron and notches forming apertures for the passage of air to the interior of the llame deflector adjacent the rear apertures in the body of the iron.
